Abstract Background To investigate the imaging findings and clinical features of multinodular vacuolating neuronal tumor (MVNT). Methods We retrospectively sought for cases that have suspicious MVNT through hospital information system. The patients’ demographics symptoms were extracted. All available images re-examined. Results Headache was most common complaint ( n = 7). Other complaints included seizure, stroke-like numbness. Conventional MRI revealed all lesions consisted tiny, sharply marginated, round or ovoid nodules following gyral contour. These hyperintense on T2 FLAIR WI, hypointense T1 WI. characterized by a lack enhancement diffusion restriction. Mass effect peripheral edema not observed. presented as an incidental finding in one case who complained gynecomastia had pituitary adenoma MRI. supratentorial—mostly right side (10/11)—and located subcortical white matter. Follow-up 11 patients with mean 14.8 months (3–40 months). No change lesion size morphology observed these follow-up images. Conclusions Radiological data suggest may exhibit indolent behavior. If asymptomatic, can be followed alone. Surgery should considered symptomatic patients.
